POPSScientists Identify Prion's Infectious Secret But prions have another characteristic that enables them to wreak havoc. They recruit other, properly folded proteins into misforming along with them, a process Lindquist calls a "conformational cascade." In many organisms, this conformational cascade creates long fibers called amyloids. (The brains of animals that have died from prion infections are literally packed with amyloid clumps.)
